Performance of the MISR instrument during its first 20 months in earth orbit

The Multi-angle Imaging SpectroRadiometer, one of five science instruments aboard NASA's Terra spacecraft, was launched into earth orbit in December 1999. Acquisition of earth imagery began in February 2000, and the quality of the data is excellent. Overall, MISR has been performing superbly, though the instrument exhibits several idiosyncrasies, some of which were anticipated prior to launch. Details regarding the in-flight performance of the instrument system are presented. Index Terms--Earth, imaging, multiangle, remote sensing.
